南水北调中线工程禹州煤矿采空区注浆处理及检测

Research on the Goaf grouting treatment and detection in Yuzhou coal mining areas in the Middle Route in the South-to-North Water Transfer Project

南水北调中线总干渠禹州段工程地质条件复杂，特别是渠道沿线穿越禹州煤矿区。禹州煤矿采空区沿线长，采空区形成时间长，地下地质条件特殊。如不对总干渠下煤矿采空区进行处理，可能对总干渠的安全运行造成不利影响。对禹州煤矿区采空区进行注浆处理，经物探及注浆检测达到了预期效果。

The geological conditions of the Middle Route in the South-to-North Water Transfer Project in Yuzhou section vary complexly, espe- cially the coal mining areas in yuzhou that have been passed through by the channel, the coal mining areas in yuzhou have formed for a long time, the geological conditions are special. If we do not make Treatment Measures on the coal mining area, which could cause subsidence channels, cracks,leaks,etc. ,then that could cause serious harm to the projects. Yuzhou mine goal areas have been grouted,detected by geophysical and Grouting achieve the anticipated effect.
